The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.

g. MyType and Object) which will still use the identity comparison. I suspect it's hamiş a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

Although I think the gains from derece boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also has some performance benefits.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

So, I am apparently wrong as unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed set of values a requirement?

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

Sair bir ifadeyle, kendi yapısal eşitlik tanılamamınızı oluşturabilir ve bu tanılamamın arabirimi C# IStructuralEquatable Temel Özellikleri onaylama IStructuralEquatable fail bir derlem türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, tamlanan IEqualityComparer bir uygulamayı kullanarak eşitliği sınav eder ve GetHashCodeeşit olan nesneler kucakin aynı kompozit kodları döndürür.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer has 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?

Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
